Project requirements

Following 200 years under Ministry of Defence ownership, Mount Wise has now been transformed into 469 luxury houses and apartments with spectacular views across Royal William Yard and Plymouth Sound. At the heart of this project is the grade II listed Admiralty House, now a boutique hotel. To complement its majestic Georgian facades, main contractor, the Leadbitter Group, enlisted the help of Jeld-Wen to provide timber windows and doors for the new build homes that not only reflected the site’s heritage, but also offered first class thermal performance.


Vertical Sliding Sash windows and Clifton double patio doorsets were specified for all of the 119 homes in phase one. Jeld-Wen designed a bespoke solution for the AOV (automatic opening vents) and MOE (means of escape) for the first floor windows to meet fire safety requirements. The affordable homes within the scheme were supplied with windows to meet the police-backed Secured by Design standards. Both the doors and windows were supplied fully finished in white to further enhance their beauty, performance and longevity.


Vertical sliding sashes that achieve a U value of 1.4 W/m²K, in line with the latest Part L requirements. In addition, these windows are also extremely easy to maintain due to their innovative easy clean mechanism, which enables the glass to be cleaned from the inside. The Clifton doorsets also offer good levels of energy efficiency, reaching a U value of 1.6 W/m²K.
